Cavity and stain are two terms that refer to dental flaws. But you may be unaware of how to spot the difference between these two dental flaws. 

If your dentist has identified that one of your teeth has a cavity, or if you notice tooth decay, it’s important to understand what you’re looking at so you can get the issue fixed before it gets worse. 

Luckily, cavity and stain are no difficult topics to understand. So, if you are one of the many confused individuals when it comes to identifying these two dental flaws, then the following article will give you the lowdown on what they are, how they are caused, and how they should be treated.

What Is A Tooth Cavity?

A cavity results from a buildup of plaque and tartar that eventually leads to tooth decay. A cavity is a permanently destroyed area within the tooth that must be filled to prevent bacteria and other germs from getting inside our body. 

It is an opening that allows bacteria to enter the tooth and cause rapid decay. There are two types of cavities, the first one being a decayed cavity and the latter one being a lesion cavity. Lesion cavities are less pronounced than other cavities as they are more challenging to spot with the naked eye.

It is important to know that dead bacteria and food particles collect on your teeth every time you floss or brush your teeth. It is what causes plaque buildup, which in turn leads to dental decay. Eventually, plaque becomes hard, and tartar is formed on it. 

However, cavity and tooth decay are some of the worst dental conditions as it leads to severe problems in your mouth and body. Cavities can be very painful to the touch. A cavity can also damage the root of your tooth and weaken it, leading to gum disease.

The cavity is especially common among older people and children as their teeth are more sensitive to plaque and tartar formation.

What Are Tooth Stains?

Tooth stains are extremely common. A stain is an area on the tooth that contains excess saliva and food debris that has not been brushed away properly. Tooth stains can appear very suddenly due to a cavity or tooth decay. 

Tooth stains can also appear due to periodontal diseases and halitosis. Another term for tooth stains is tooth discoloration. The teeth that have been discolored due to tooth stains can appear lighter, darker, or in different shades of color. 

Dental stains are found in 70-75 percent of adults. Discolored or stained teeth can be embarrassing if they make unwanted appearances during social gatherings and professional meetings. This dental issue can also cause a very negative impression of you, affecting your self-esteem.

What Are The Symptoms Of A Tooth Cavity And Tooth Stains?

A cavity is characterized by a hole in the tooth that is caused by bacteria and decayed food debris. A cavity will usually start at the base of your teeth and then slowly move up towards the surface of your teeth. Eventually, the hole will continue to get bigger and bigger until it extends through your entire tooth. However, a few prominent symptoms of a tooth cavity are:

  • The area will feel sensitive to touch.
  • Persistent toothache that causes difficulty with swallowing, talking, and even sleeping.
  • A bad taste in your mouth.
  • A Hole or dark spot on your teeth.
  • Swelling and bleeding of the gums around the affected tooth.

A stain is characterized by an area of discoloration on your teeth located on your teeth’ inner surface. Stains are also not clear tooth decay because they are often found in less noticeable areas than cavities. 

However, a few prominent symptoms of a tooth stain are:

  • You may notice that your teeth look dirty or stained even after brushing or flossing them.
  • Your teeth may look gray or grayish brown.
  • The stain will become more pronounced over time.
  • The stain may appear on your gums or in between your teeth, known as dental staining.

The Difference In The Appearance Of A Cavity Vs. Stain

To notice any dental flaw, you must understand the difference between a stain and a cavity. To spot the differences between these two dental flaws, you need to pay close attention to common oral behaviors such as brushing, flossing, and eating.

Cavity 

You can spot a cavity by seeing a white spot on your tooth. A cavity is what dentists refer to as demineralization, an area that has lost the minerals and nutrients found in the enamel. 

Demineralization is a sign of dental decay, and it can become more pronounced such as turning brown or black, which gives the appearance of a cavity. A cavity is a large area that has been destroyed. The color of a cavity will most likely be brown, and it can turn black if left untreated.

Tooth stains  

On the other hand, you can spot a stain by seeing an area with more color than the rest of your teeth. A tooth stain is different from a cavity because it results from your oral hygiene status and how much your teeth have been exposed to certain types of food and drink. 

Tooth stains are often found between teeth and are less noticeable than cavities. Discolored or stained teeth are primarily found in the space between your teeth. Stains will also appear darker compared to the rest of your teeth.

What Are The Causes Of Tooth Cavities And Stains?

Tooth cavities and stains can be traced back to poor oral hygiene. If you do not properly clean and maintain your teeth, tooth decay and cavities are likely. However, other factors that are thought to cause tooth cavities include:

  1. Sugar– A high in sugar diet can lead to tooth cavities. Sugar encourages the growth of harmful bacteria that break down the teeth, forming plaque. The byproducts of plaque are acids that will eat away your enamel, leaving a cavity behind.
  2. Lack of nutrients in the diet– If your diet lacks healthy calcium, zinc, and fluoride sources, your enamel will become weaker and break away.
  3. Dry Mouth– Dry mouth is a common cause of cavities. It can result from mouth breathing and certain medications you may take, such as depression or anxiety.
  4. Poor dental care– A lack of regular dental visits will allow plaque and tartar to build upon your teeth. It can result in a tooth cavity.
  5. Acid Reflux– Heartburn or acid reflux will only increase your risk of developing a tooth cavity. The stomach acids regurgitated into the mouth can damage your enamel, leading to cavities.
  6. Genetics– Some studies suggest that genetics may play a role in tooth cavity because it may higher the risk of developing cavities and the likelihood of experiencing sensitivity problems after consuming hot or cold food and drink.

Moreover, tooth stains are linked to poor oral hygiene resulting from other dental issues, and their symptoms are not always visible. Several conditions can cause tooth stains, some of which include:

  1. Foods/drinks– Foods and beverages such as coffee, tea, cola, red wine, berries, blueberries, curry powder, and smoking can discolor your teeth. 
  2. Medical Conditions– Medications taken for medical conditions such as arthritis or heartburn may also discolor your teeth by changing how they absorb water.
  3. Aging– The older you are, the older your teeth become over time. It causes them to get darker and turn yellow or brown with age.
  4. Diseases– Diseases such as hepatitis, gout, kidney disease, and lupus can cause a symptom known as tooth discoloration.
  5. Family history– If your parents have dark or discolored teeth, you will likely inherit the same trait from them.
  6. Dental care– If you are not taking good care of your teeth, you may eventually notice your teeth getting darker over time and developing stains or cavities.
